Quoting Paul Shaw:
“Columbia's copy of this specimen book does not have the page with Gothic No. 5 (pg. 56 here). The bottom of that page has the address “55 Water Street” while the title page and all of those in the Columbia copy have “Spring Lane”. Thus, this Internet Archive copy (from the Boston Public Library) is a later edition with added pages. I think it is from 1867 as the pencil note on the back of the title page indicates since newspaper ads as early as February 1867 have the 55 Water Street address. The 1864 Boston Almanac has the company at Spring Lane but the 1867 almanac confusingly has it at Spring Lane with John. K. Rogers & Co. at 55 Water Street. However, newspapers, city directories, and other sources say 55 Water Street in 1865. In 1871 the foundry moved to 87 Kilby Street.”
